Paul Eggert 3562e384 2017-09-16T13:03:36 Prefer https: URLs In Gnulib, Emacs, etc. we are changing ftp: and http: URLs to use https:, to discourage man-in-the-middle attacks when downloading software. The attached patch propagates these changes upstream to Automake. This patch does not affect files that Automake is downstream of, which I'll patch separately. Althouth the resources are not secret, plain HTTP is vulnerable to malicious routers that tamper with responses from GNU servers, and this sort of thing is all too common when people in some other countries browse US-based websites. See, for example: Aceto G, Botta A, Pescapé A, Awan MF, Ahmad T, Qaisar S. Analyzing internet censorship in Pakistan. RTSI 2016. https://dx.doi.org/10.1109/RTSI.2016.7740626 HTTPS is not a complete solution here, but it can be a significant help. The GNU project regularly serves up code to users, so we should take some care here.
Reiner Herrmann 7c25c996 2017-09-15T11:43:53 mdate-sh: Ensure reproducible time output This change fixes automake bug#20314. 'mdate-sh' pretty-prints the modification time of a file. But it's output can vary depending on the timezone of the caller. Someone in timezone GMT-12 will get a different result (day) than someone in timezone GMT+12. As this output is also used to create/update stamp files, which influence the further build process, the build result can vary. * lib/mdate-sh: Set 'TZ' to UTC which ensures reproducible output. * NEWS: Announce bug fix.

Stefano Lattarini 08849db8 2015-01-03T01:33:45 deps: fix corner-case "make distclean" bug Assume we have package satisfying the following conditions: (1) automatic dependency tracking is enabled; (2) the 'subdir-objects' Automake option is enabled; (3) the package uses a recursive make setup. Also assume that: (a) a subdir Makefile declares a foo_SOURCES variable containing a source file in the parent directory; (b) that parent Makefile declare a compiled program itself. Then BSD and Solaris make used to fail when running "make distclean", because the 'distclean' target of the subdir Makefile removed the whole '.deps' directory before the parent Makefile was done with the included '.Po' makefile fragments in that directory. This issue was revealed by failures in the 'subobj-vpath-pr13928.sh' test when those make implementations were used. We fix the issue by ensuring the 'distclean' target of any Makefile only removed the '.Po' makefile fragments included by it, rather than the whole '.deps' directory where such files resides. This change should be the last step in fixing automake bug#13928 for good. * bin/automake.in (handle_languages), lib/am/depend.am: Adjust to implement the new 'distclean' logic. * t/pr224.sh: Adjust to avoid a spurious failure. * PLANS/subdir-objects.txt: Update.

Stefano Lattarini 6a675ef1 2014-12-24T10:57:17 deps: 'subdir-object' option now works when foo_SOURCES contains $(var) Following a suggestions of Johan Kristensen, we have config.status use 'make' invocations rather than Makefile-parsing 'sed' hacks to bootstrap the dependency-tracking '.Po' and '.Plo' makefile fragments. To handle the inclusion of such files that are still missing when make is first we basically generate a temporary Makefile without these includes, and call 'make' on that Makefile. This fixes the serious bug bug#13928, which was an hard blocker to make the behavior mandated by the 'subdir-object' active by default (which we want to do in Automake 2.0). The issue has also been reported in bug#15919. * NEWS, THANKS: Update. * bin/automake.in (handle_languages): Add a trailing "marking" comment ("# am--include-marker") to the generated Makefile lines issuing 'include' directives for the dependency-tracking '.Po' and '.Plo' makefile fragments. Also rename the generated Makefile variable 'am__depfiles_maybe' to the clearer 'am__maybe_remake_depfiles'. Minor unrelated refactoring. * lib/am/configure.am: Adjust to account for the 'am__depfiles_maybe' -> 'am__maybe_remake_depfiles' renaming. * lib/am/depend.am: Add rules to generate a dummy version of all the dependency-tracking '.Po' and '.Plo' makefile fragments. * m4/depout.m4: Use make invocations rather than Makefile-parsing sed hacks to bootstrap the dependency-tracking '.Po' and '.Plo' makefile fragments. We still use some sed trickery in order to remove the inclusion of the still non existing .Po and .Plo files from the Makefile we invoke make upon; this is done stripping lines that contain the magic string "# am--include-marker". * m4/make.m4 (AM_MAKE_INCLUDE): Given that now automake generates Makefiles containing include statements with trailing comment, adjust the checks done here to make sure $MAKE support that; e.g., "include foo.mk # comment" rather than just "include foo.mk". Also refactor and adjust to leave better debugging info in config.log. * t/postproc.sh: Rename ... * t/depend-postproc.sh: ... to this, and adjust and enhance. * t/list-of-tests.mk (handwritten_TESTS): Adjust. (XFAIL_TESTS): Remove 't/subobj-indir-pr13928.sh', which is now succeeding. * t/subobj-indir-pr13928.sh: Simplify slightly, now that we expect it to pass. * t/depcomp8a.sh: Adjust grepping check to account for the changes in the generated Makefile, and tp be somewhat more robust in light of possible future modifications. * t/depcomp8b.sh: Likewise. * t/subobj11b.sh: Likewise. * t/subobj11c.sh: Likewise. * t/extra-sources.sh: Likewise. * t/lex-depend-grep.sh: Likewise. * t/lex-depend-cxx.sh: Add a command to help debugging in case of test failure.

Stefano Lattarini 01a7a4a7 2014-12-23T18:39:32 dist: fix bug#18286 "distcheck fails to detect missing files" BTW, this issue had been already reported in the past: http://lists.gnu.org/archive/html/automake/2006-09/msg00008.html http://lists.gnu.org/archive/html/automake/2013-01/msg00049.html "make distcheck" could sometimes fail to detect missing files in the distribution tarball, especially in those cases where both the generated files and their dependencies are explicitly in $(srcdir). An important example of this are *generated* makefile fragments included at Automake time in Makefile.am. A basic example: # -*- Makefile.am -*- $(srcdir)/fragment.am: $(srcdir)/data.txt $(srcdir)/preproc.sh cd $(srcdir) && $(SHELL) preproc.sh <data.txt >fragment.am include $(srcdir)/fragment.am ... If the use forgot to add data.txt and/or preproc.sh in the distribution tarball, "make distcheck" would have erroneously succeeded! The reason is that, while $(srcdir)/data.txt does not exist, make also looks in $(srcdir)/$(srcdir)/data.txt, and in the distcheck-issued VPATH build where $(srcdir) is '..', that file exists, as it is part of the original development directory. * t/distdir.am (distcheck): Adjust to have the build directory be '$(distdir)/_build/sub' rather than just '$(distdir)/_build'. Thanks Nicola Fontana for the suggestion. * t/distcheck-pr18286.sh: Enhance and tighten a little. * t/list-of-tests.mk (XFAIL_TESTS): Remove 't/distcheck-pr18286.sh', as it's now passing. * t/subdir-am-cond.sh: Adjust to avoid a fully spurious failure due to the new distcheck semantics. * t/subdir-ac-subst.sh: Likewise. * t/dejagnu-relative-srcdir.sh: Likewise. * t/txinfo-builddir.sh: Likewise. * NEWS: Update.

Stefano Lattarini 55270ac3 2014-12-23T13:10:21 include: fix bug in handling of user-defined makefile fragments generation If a user defined one single Makefile fragment to be included (via Automake includes) in his main Makefile.am, and gave a rule to generate that file from other data, Automake used to spuriously complain about with something like "overrides Automake target '$(srcdir)/foo.am". This change remove that spurious error (via a simple hack rather than a systematic change, but oh well). * lib/am/configure.am (%MAKEFILE-IN-DEPS%) [?HAVE-MAKEFILE-IN-DEPS?]: Add a trailing "$(am__empty)" to the list of targets, which is enough to trick Automake into not complaining about "duplicated targets" in case the '%MAKEFILE-IN-DEPS%' list expands to a single target that is also declared in some user-defined rule. * t/list-of-tests.mk (XFAIL_TESTS): Remove now-passing test 't/am-include-only-one-generated-fragment.sh'. * NEWS: Update.

Stefano Lattarini e7c14d96 2014-12-19T15:10:09 Improve detection of GNU make, avoiding "Arg list too long" errors. Such errors could take place when the main makefile included too many sub-makefiles, making $(MAKEFILE_LIST) too long and causing the recipes $(am__is_gnu_make) to exceed the shell's command-line length limits. This is not a theoretical issue: it could happen for projects having lots of C/C++ sources and using automatic dependency tracking, which created an included .Po sub-makefile for each of such sources.

Stefano Lattarini 52e64045 2013-07-21T17:58:05 automake: account for perl hash order randomization Try to explicitly order the keys of some perl hashes when looping on them to do sanity/correctness checks and possibly display warning messages; this should ensure a more reproducible output. Not really a big deal, but I prefer to keep the order of such output reproducible if possible. Issue revealed by spurious testsuite failures with perl 5.18, as reported in automake bug#14891.

Apparently, some packages got in the habit of relaying all the options passed to the original ./configure invocation through to the configure invocations in "make distcheck".

But with /usr/xpg4/bin/sh, the shell complains like this: "test: argument expected", and returns a non-zero exit status. This caused testsuite failures in several lisp tests.
